This invention relates to an improvement in a combined tooth brushcontainer and tooth paste holder and dispenser.

The main object of the invention provides a tooth paste receptaclehaving a piston movable therein, said piston having a passagetherethrough by which the tooth paste is deposited upon the bristles ofthe tooth brush.

A further improvement incorporates the op. eration of the piston fordispensing the paste as by pressure exerted on the piston from theforward end of the tooth brush, whereby the brush is in correct positionto receive the expelled tooth paste.

A further object of the invention provides a tooth paste holder of ovalshape to prevent any rotation of the paste-expelling piston.

A further improvement provides a piston being recessed at both front andrear sides, and having a relatively thick central web portion, the innerface side of the web sloping from bottom to top to direct paste upwardlyto the outlet channel within the upper portion of the piston.

Other objects and advantages will become apparent from the followingdescription and accompanying drawings, in which? Fig. 1 is a side viewyof the assembled tooth paste holder and tooth brush container;

Fig. 2 is a View, partly in section, showing the speciiic structure ofthe piston, the 'brush con,- tainer removed and the brush end in contactwith the outer face of the piston;l

Fig. 3 is a longitudinal sectional view of the paste holder and toothbrush container, `the brush and piston shown in full lines;

Fig. 4 is a section on the line 4-4 of Fig. 3; and

Fig. 5 is a vertical longitudinal section through the piston.

Referring to the drawings, in which like numerals Ihave been used todesignate similar parts throughout the various views, the container forholding the tooth paste is shown at 6 and is provided at one of its endswith a lling opening closed as by a rubber stopper 1 having an annularrecess 8 into which ts the circular iiange 9 surrounding the containeropening.A The forward end of the paste container 6 terminates in areduced annular ange I forming a shoulder II. The tooth brush of thepresent' invention consists of the usua'l head I2 and bristles I3, thehead extending into a reduced vhandle portion I4 of solid plasticconstruction, said handle flaring to an enlarged part I5, the enlargedpart I having attached thereto as by fusion or the like an enlargedcup-shaped terminal I6, the terminal portion I6 having all insidediameter of sucient size to provide for frictional fitting of the samewith the flange part I0 of the paste container 6, the annular outersurface I'I of the eupshaped member I6 abutting the shoulder II when thebrush is mounted thereon.

A brush cover or container I8 has a closed end I9 and en open. end which'latter friotifonally engages the outer ared surface I5 of the brushhandle Ito thereby protect the brush when the same is stored or not inuse, as in the Fig. 3 con dition. However, it is contemplated that whenthe brush is in use the container Ia canbe used in the capacity of abrush handle extension, in which position the container I8 is removedfrom the portion I5 and its open end is frictionally engaged within theopen cup-shaped portion I6 of the handle, of course, after the same hasbeen removed from the paste container 6 and thereby provides better andeasier manipulation of the brush during the cleaning operation. Itlikewise becomes eiective for use as a handle when the brush is beingused for forcing the piston to dispense paste upon the brush bristles,The brush casing I8 is provided adjacent its closed end with a*yplurality of longitudinally extending cuts 2|, four irl numben extendingfrom the closed end I3 inward of the casing to provide for ventilostionof the brush bristles when the brush con-.- tainer is mounted to enclosethe brush.

piston or plunger 22 is of oval shape in erOSs-Seetor-1 and isfrietionallv mounted for reciprocation within the paste container 6. Theplunger is recessed at its front end as seell at 23 and likewise at itsrear end at 24 to form a connecting web 25 having its outer wallslightly concaved as shown at 26 while the opposite wall 21 is inclinedupwardly for a purpose later to appear.

The outer surface of the piston is oval in form to rctionally engage theinside walls of the lpaste container 6,. the walls 28 surrounding therecess 24 being beveled to a Vfeather edge .29 whereby they will performa certain scraping action along the. inner sur-face of Ithe container 6and thus prevent the escape of the paste or like contents Qi theoontainer'from leaking therepast. The upper portion. of the plusser 22is, thickened at 30. as seen in Fig. i and said thickened portion is.provided with a longitudinal bore or .passage 13A through sastcnassesupon. inward movement of the piston, the upwardly inclined wall 21tending to direct the paste contents upward to the passage opening 3l.The concaved surface `upon the bristles.

2B of the piston provides a surface which is adapted to receive thefront end of the brush head I2, which brush, upon being pressed in- YWardly to force the piston inwardly, causes the discharge of pastethrough the passage SI onto the brush bristles I3. It is, of course, tobe understood that when the piston is being moved to dispense paste, thebristles are held directly under the discharge end of the passage 3|.

In the operation of the device, the rubber stopper 'I is first removedand the open end of a paste tube is inserted therein to deposit thecontents thereof within the container 6, the piston being forced backtowards the open end of the container until it is stopped by abuttingthe inner face surface of the cup-shaped member I6. Thereupon, the llingtube is removed and the rubber stopper exed within the opening of thecontainer. The tooth brush cover is removed, whereupon the tooth brushis removed from the open end of the paste container and turned end forend, in which position the free end of the brush head I2 can be pressedagainst the surface 26 of the piston lto force the same inwardly until asufficient amount of paste has been deposited The brush is then removed,turned end for end and again fitted to the container 6, which acts as ahandle, and the usual teeth cleaning operation is performed. After use,the cover I8 is then tted in place over the brush head.

As will be understood from an inspection of Fig. 3,'the ange 9 at therear end of the container 6 about the plug receiving opening serves as astop to limit outward movement of the piston, or plunger, 22. Should itbe found desirable to remove the plunger 22, as for instance forcleaning, it is a simple matter to remove the plug I and using a pencilor the like, force the plunger outwardly through the open en-d of thecontainer 6. i

It will therefore be'seen that I have provided a compact and combinedtooth brush holder and paste dispenser which is a self-contained unitand is capable of being carried opon the person, and in Vwhich the toothpaste and tooth brush are embodiedrin a single unit which is extremelyhandy and compact and thereby eliminates the usual practice of requiringboth a paste container land tooth brush, the invention being highlyuseful by persons taking trips or While travelling.

A preferred form of the invention has been illustrated vbut itis'contemplated that various changes and modifications are possiblewithin the scope of the following claims.
